内容简介

Ultra-Fine Grained Steels discusses results of the New Generation Iron and Steel ,Materials research project funded over the last ten years. Modern sustainability requirements want that iron and steel must meet tour conditions:stronger, longer service life, leading-edge manufacturing technology (low cost, material and energy efficient), and environmentally sound (waste recycling, reduced carbon dioxide emission). Therefore, new generation iron and steel materials featuring "double strength and double service life" are needed (labeled "ultra steels" in Japan).
